Definitions

  • This disclosure relates to a wind velocity sensor for a vehicle.
  • Prior art wind velocity sensors can be mounted on vehicles to estimate wind velocity.
  • certain prior art wind sensors exhibit significant measuring error when an off-road vehicle moves in a work area or field.
  • a wind velocity sensor comprises a lower platform and an upper platform. Pillars are positioned or connected between the upper platform and the lower platform. Ultrasonic sensors are secured to corresponding ones of the pillars. A lower guard member extends outwardly from a reference ultrasonic sensor by a radial distance greater than a radial separation between any pair of the ultrasonic sensors.
  • FIG. 1 is a perspective view of a first embodiment of the wind velocity sensor.
  • FIG. 2 is a perspective view of a second embodiment of the wind velocity sensor.
  • FIG. 3 is a block diagram of a the electronic assembly of the wind velocity sensor of FIG. 1 or FIG. 2 .
  • a wind velocity sensor 11 comprises a lower platform 32 and an upper platform 34 . Pillars 40 are positioned or connected between the upper platform 34 and the lower platform 32 . Ultrasonic sensors ( 10 , 12 ) are secured to corresponding ones of the pillars 40 . A lower guard member 38 extends outwardly from a reference ultrasonic sensor 10 by a radial distance 103 greater than a radial separation 101 between any pair of the ultrasonic sensors ( 10 , 12 ).
  • turbulence created by the vehicle's irregular shape can distort or change the airflow detected by one or more ultrasonic sensors ( 10 , 12 ), which can cause it or them to read inaccurate wind velocity, including the wind direction, the magnitude of the wind speed, or both.
  • the lower guard member 38 is positioned below the ultrasonic sensors ( 10 , 12 ) and the upper guard member 36 is positioned above the ultrasonic sensor to straighten and guide the airflow detected by one or more sensors ( 10 , 12 ), while deflecting turbulence from above or below the guard members ( 36 , 38 ).
  • a lower platform 32 comprises a substantially cylindrical structure, a substantially polygonal structure, or substantially rectangular structure.
  • the upper platform 34 comprises a substantially cylindrical structure, a substantially polygonal structure, or substantially rectangular structure.
  • Either the lower platform 32 or the upper platform 34 may be formed by joining a first housing member and a second housing member to house an electronics assembly 112 , save the ultrasonic sensors ( 10 , 12 ).
  • electronics assembly 112 is illustrated in dashed or phantom lines in FIG. 1 within the lower platform 32 , although other embodiments can fall within the scope of the appended claims. The electronics assembly 112 is described in more detail in conjunction with FIG. 3 .
  • a set pillars 40 are positioned between or connected to the upper platform 34 and the lower platform 32 .
  • each pillar may have any cross-sectional shape such as substantially elliptical, rectangular, triangular, or otherwise.
  • each pillar 40 has a notch or recess (e.g., semi-cylindrical notch) for receiving or mounting a corresponding ultrasonic sensor within the notch or recess.
  • the ultrasonic sensors ( 10 , 12 ) are secured to corresponding ones of the pillars 40 by fasteners, a snap-fit connection, or adhesive bonding, for example. At least two ultrasonic sensors 10 are required to provide an estimate wind velocity, although three or more ultrasonic sensors ( 10 , 12 ) can provide more accurate estimates. Ultrasonic sensors 12 are shown as dashed lines in FIG. 1 , FIG. 2 and FIG. 3 because the ultrasonic sensors are optional.
  • a lower guard member 38 extends outwardly by a radial distance 103 that is substantially equal to the radial distance 103 of the upper guard member 36 .
  • the lower guard member 38 extends outwardly from a reference ultrasonic sensor 10 (or any arbitrary ultrasonic sensor) by greater radial distance 103 than a radial separation 101 between any pair of the ultrasonic sensors ( 10 , 12 ).
  • the upper guard member 36 extends outwardly from an ultrasonic sensor ( 10 , 12 ) by a radial distance 103 greater than a radial separation 101 between any pair of the ultrasonic sensors ( 10 , 12 ). If the ultrasonic sensor is co-located with a pillar 40 , the radial distance 103 and the radial separation 101 may be measured from a central vertical axis 55 of each pillar 40 , for example.
  • the upper guard member 36 and the lower guard member 38 may have virtually any perimeter shape (e.g., curved, circular, elliptical, ring-shaped, scalloped, or polygonal) so long as the upper guard member 36 and the lower guard member 38 are substantially planar or generally flat. As illustrated, in FIG. 1 , the upper guard member 36 is substantially annular and substantially planar. Similarly, the lower guard member 38 is substantially annular and substantially planar. In certain embodiments, the upper guard member 36 may be referred to as a disc or disc-shaped member; the lower guard member 38 may be referred to as a disc or disc-shaped member.
  • the upper guard member 36 is secured to at least a portion of a lower surface 38 of the upper platform 34 .
  • the upper guard member 36 is adhesively bonded to at least a portion (e.g., an outer ring surface) of the lower surface 38 of the upper platform 34 .
  • the lower guard member 38 is secured to at least a portion of an upper surface 35 (e.g., an outer ring surface) of the lower platform 32 .
  • the lower guard member 38 is adhesively bonded to at least a portion of the lower surface 35 of the upper platform 34 .
  • the wind velocity sensor 11 is capable of mounting on a vehicle or implement, or a stationary structure.
  • the wind velocity sensor 11 is well suited for mounting on agricultural, construction, forestry and other off-road work vehicles, or its or their associated implements.

  • the wind velocity sensor 111 of FIG. 2 is similar to the wind velocity sensor 11 of FIG. 1 , except in FIG. 2 each of the upper guard member 136 and the lower guard member 138 has a shoulder, collar or hub. Like elements in FIG. 1 and FIG. 2 are indicated by like reference numbers.
  • the upper guard member 136 has a shoulder, collar or hub 52 for mating with an outer perimeter of the upper platform 34 and the lower guard member 138 has a shoulder, collar or hub 52 for mating with an outer perimeter of the lower platform 32 .
  • the shoulder, collar or hub 52 is press-fitted onto the outer perimeter of the upper platform 34 to secure the upper guard member 136 to the upper platform 34 .
  • the shoulder, collar or hub 52 is press-fitted onto the outer perimeter of the lower platform 32 to secure the upper guard member 136 to the lower platform 32 .
  • the shoulder, collar or hub 52 of the lower guard member 138 or the upper guard member 136 may be adhesively bonded, welded, or fastened (with fasteners) to the lower guard platform or the upper guard platform, respectively.
  • the lower platform 32 , the upper platform 34 , or both may comprise an electronics enclosure with a first enclosure portion and a mating second enclosure portion that encloses the electronic assembly 112 illustrated in the block diagram.
  • the first enclosure may nest with the second enclosure portion, or the first enclosure portion may comprise a lid for mounting on a container that embodies the second enclosure portion.

  • a driver 16 is coupled to the sensor terminals to drive the ultrasonic sensor ( 10 , 12 ) to produce or transmit a sound pulse or noise pulse at the transmission time.
  • Each ultrasonic sensor ( 10 , 12 ) can generate or transmit a sound pulse or noise pulse within a measurement frequency band (e.g., approximately 150 Hz to approximately 450 kHz).
  • Each ultrasonic sensor ( 10 , 12 ) can receive, detect or sense a sound pulse or noise pulse within a measurement frequency band (e.g., approximately 150 Hz to approximately 450 kHz).
  • Input terminals of the multiplexer 14 are coupled to the sensor terminals of one or more ultrasonic sensors ( 10 , 12 ).
